Shows rainfall but hasn't rained all day

My 5 in 1 pro weather station rain gauge shows I have received .3 inches of rain but it hasn't rained all day. Been working great, I installed on Thanksgiving 2015. It is a 06014RM sensor, any thoughts on this.

If the sensor is not tightly secured to its mount, high wind gusts can cause it to move and register what is known as "phantom rain." Or if you took it down to change the batteries, you might have shaken it and caused the rain buckets to tip back and forth. I just did that yesterday and wound up with .05" of non-existent rain.

An other thing that could have happened is that if this unit is close to any trees or buildings, squirrels like to mess with the sensors as well. Any kind of bump from an animal could cause erroneous readings as well. Please keep an eye out on this and if you continue to notice this problem and its not wind or animals, call us at 877-221-1252.
